"We sure are pleased," he said. "Basically our family has gotten so much support from each other and friends. ... The local church took us under their wing and my co-workers have been so kind to all of us."

Addison has a 4-year-old biological brother who has been in counseling since his mother died.

"He still thinks about his mother and misses her," said Cox, 37. "But talking to a 4-year-old kid about anything can be difficult."

Addison also has two teenage stepbrothers. Cox's mother, who is from Texas, has been living with the family to help out for the last nearly two years.

The cancer has affected the child's brain, shoulder, lungs, kidney, liver, leg, and even the back of her tongue. She has had chemotherapy, radiation and brain surgeries at Phoenix Children's Hospital, which is hosting a telethon to benefit the family.

The toddler has been on chemotherapy for 20 months and has undergone radiation. A month ago she had two brain surgeries four days apart.

A fundraiser by the police department where Briana Cox worked has helped the family deal with their financial needs. "Most has been covered by medical insurance, but it's the cost of day-to-day life that really hammers us," said Cox.

So far, Addison has progressed well, understanding speech and saying a few words, like any child her age, according to her father.

"That gives you a lot to look forward to and know she's still doing this well, it just kind of keeps you going," said James.
